Title Data on dolphin occurrence (from CPODs) for analyses of responses of dolphins to piling activity
Downloaded 4 times
Description 1. Data on dolphin occurrence (from CPODs) for analyses of responses of dolphins to piling activity (see Fig. 1, Fig. 4a & Fig. 7a,b,d,e). Filename = “dolphin presence & DPH12 CPOD data 2013-2014.txt” Fourteen columns = Location, Date, Julday, Presence, DPH12, Latitude, Longitude, Line_sight, Dist_impact, Year, Block, Impact, Vibration, Area. Julday is Julian day. Presence is the presence or absence (coded 1 or 0) of dolphins on each day of sampling (from 06:00 to 18:00). DPH12 is the number of hours within the 12-hour period (from 06:00 to 18:00) in which dolphins were detected. Line_sight indicates whether or not a location is within line of sight of the piling location (coded 1 or 0). Dist_impact is the minimum at-sea distance between each location and the piling location in meters. Block is the year concatenated with Julian day, used as the grouping factor for the GEEs (at the larger temporal scale). Impact is coded as two levels: 1 (impact piling), 0 (no impact piling). Vibration is coded as two levels: 1 (vibration piling), 0 (no vibration piling). Area is coded as two levels: 1 (within the Cromarty Firth), 0 (outside the Cromarty Firth).

Title Data on dolphin encounter durations (from CPODs) for analyses of responses of dolphins to piling activity
Downloaded 7 times
Description Data on dolphin encounter durations (from CPODs) for analyses of responses of dolphins to piling activity (see Fig. 7c,f). Filename = “dolphin encounter durations CPOD data 2013-2014.txt” Fourteen columns = Location, Year, Durations, Date & Time, Hour, Latitude, Longitude, Line_sight, Dist_impact, Julday, Block, Impact, Vibration, Area. Durations is the duration (s) of each dolphin encounter that started between 06:00 to 18:00. Date & Time is the start time of each encounter. Hour is the hour in which each encounter started. Line_sight indicates whether or not a location is within line of sight of the piling location (coded 1 or 0). Dist_impact is the minimum at-sea distance between each location and the piling location in meters. Julday is Julian day.
